New gameplay classes, Slate and Canvas user interface elements, and editor functionality can be written with C++, and all changes will be reflected in Unreal Editor after compiling with either Visual Studio or XCode. The Blueprints visual scripting system is a robust tool which enables classes to be created in-editor through wiring together function blocks and property references. C++ classes can be used as a base for Blueprint classes, and in this way programmers can set up fundamental gameplay classes that are then sub-classed and iterated on by level designers. ## Getting Started [REGION:features third] [OBJECT:Role] [PARAM:icon] ![](%ROOT%/start_icon.png)(convert:false) [/PARAM] [PARAM:title] Programming Quick Start [/PARAM] [PARAM:path] [RELATIVE:Programming/QuickStart] [/PARAM] [PARAM:description] %Programming/QuickStart:description% [/PARAM] [PARAMLITERAL:id] quickstart [/PARAMLITERAL] [/OBJECT] [OBJECT:Role] [PARAM:icon] ![](%ROOT%/prog_icon.png)(convert:false) [/PARAM] [PARAM:title] Intro to C++ in Unreal [/PARAM] [PARAM:path] [RELATIVE:Programming/Introduction] [/PARAM] [PARAM:description] %Programming/Introduction:description% [/PARAM] [PARAMLITERAL:id] intro [/PARAMLITERAL] [/OBJECT] [OBJECT:Role] [PARAM:icon] ![](%ROOT%/prog_role_icon.png)(convert:false) [/PARAM] [PARAM:title] %Programming/Tutorials:title% [/PARAM] [PARAM:path] [RELATIVE:Programming/Tutorials] [/PARAM] [PARAM:description] %Programming/Tutorials:description% [/PARAM] [PARAMLITERAL:id] tutorials [/PARAMLITERAL] [/OBJECT] [/REGION] [OBJECT:TopicButtonList] [PARAM:icon] ![](%ROOT%/api_icon.png)(convert:false) [/PARAM] [PARAM:title] Unreal Engine API Reference [/PARAM] [PARAM:description] [/PARAM] [PARAM:links] * [Unreal Engine API](https://docs.unrealengine.com/latest/INT/API/index.html) * [Core API](https://docs.unrealengine.com/latest/INT/API/Runtime/Core/index.html) * [Core UObject API](https://docs.unrealengine.com/latest/INT/API/Runtime/CoreUObject/index.html) * [Engine API](https://docs.unrealengine.com/latest/INT/API/Runtime/Engine/index.html) [/PARAM] [/OBJECT] [OBJECT:TopicButtonList] [PARAM:icon] ![](%ROOT%/prog_icon.png)(convert:false) [/PARAM] [PARAM:title] Unreal Engine Architecture [/PARAM] [PARAM:description] Whether you are programming with C++, Blueprints, or a combination of the two, the underlying Unreal architecture is the same.
